Exchange-traded funds (ETFs) function similarly to stocks; however, investors buy and sell ‘units’ instead of ‘shares.’ These ‘units’ can be exchanged like stocks but can also be created or destroyed based on investor demand. Each week, we track the changes in shares outstanding to pinpoint ETFs that are experiencing significant inflows (often resulting in the creation of new units) or outflows (often involving the destruction of old units). The creation of units necessitates purchasing the underlying holdings of the ETF, while the destruction implies selling those holdings. Consequently, substantial flows can also influence the individual components held within the ETFs.
